Is James Gunn Already Writing His Third Superman Movie? New Report Points to Yes

James Gunn’s next DC movie after ‘Man of Tomorrow’ has been one of the franchise’s biggest open questions, and a new report suggests he isn’t ready to leave Superman behind just yet. ‘Superman: Man of Tomorrow’ wrapped filming in August and is now deep in post-production ahead of its July 9, 2027 release. David Corenswet returns as the Man of Steel, who is forced to team up with Nicholas Hoult’s Lex Luthor.

The sequel already has a big threat lined up. Superman and Lex form an uneasy alliance to face Brainiac, played by Lars Eidinger, one of DC’s most powerful and intelligent villains. Gunn has also described the film as being about Clark and Lex at its core.

Now, attention is turning to what comes after that. According to insider Daniel Richtman, Gunn’s next DCU film is reportedly ‘Superman 3’. The report comes shortly after Gunn confirmed that he is already writing his next movie, though he hasn’t said what it is.

The confirmation came on Threads last month. When a fan asked whether he was ready to write his next film, Gunn said he was already in it, joking that he needed something to do while waiting for the assembly cut. He also confirmed the assembly cut of ‘Man of Tomorrow’ is now finished.

Gunn hasn’t revealed what he’s writing, and outlets have been careful about guessing. World of Reel suggested the next script could be a third Superman installment, but that was presented as educated speculation rather than a confirmed plan. Richtman’s report adds more fuel to that idea, though it hasn’t been officially confirmed either.

There are other possibilities too. ScreenRant pointed out that if Gunn is writing something already in development, it could be ‘The Brave and the Bold’, the ‘Wonder Woman’ reboot, or ‘The Authority’, which Gunn previously said was shelved because the script didn’t work for the larger DCU.

The idea of another Superman film has excited plenty of fans. After Gunn’s update, some on X predicted a ‘Justice League’ movie, while others guessed it would be another Superman story. One fan even suggested Corenswet could become the first Superman since Christopher Reeve to get a full trilogy.

A third film would also fit Gunn’s track record so far. He has written and directed both Superman films while hiring other filmmakers for most of the surrounding DCU projects, so a new Superman script would be a natural next step for him.

The franchise’s results have been mixed so far. ‘Superman’ launched the new DC Universe with $618 million worldwide, but ‘Supergirl’ struggled with $126 million. ‘Clayface’, a more modestly budgeted horror film, debuted in October.

There’s also uncertainty behind the scenes. Paramount’s acquisition of Warner Bros. was expected to close soon, but Gunn and his co-chair Peter Safran are staying on at DC Studios and moving ahead with their plans. Knowing Gunn is already working beyond his Superman sequel is a good sign that the DCU isn’t ending, especially with the Skydance era on its way.

Gunn has also been busy shooting down other rumors. He recently dismissed fan-made poster art featuring Adria Arjona as Wonder Woman, and he shut down speculation that Jensen Ackles would play the DCU’s Batman.

For now, ‘Man of Tomorrow’ remains the priority, with Superman and Lex taking on Brainiac next summer. If Richtman’s report is right, though, Corenswet’s time in the cape may last longer than just 2 movies.
